You guys are going to love this unique cake mix brownie recipe! I’ve loved it ever since I was a little girl. My mom has been making these chocolate chip brownie bars for years. She always called them Lazy Day Bars. Quite the perfect name because this is the brownie recipe for all of you lazy bakers. This is a one bowl brownie recipe and you only need a handful of ingredients to bake these up.
Ingredients In Chocolate Chip Brownie Bars
The most important ingredient for this brownie bar recipe is a boxed German chocolate cake mix. Any brand will do. I have also successfully made this recipe with a box of regular chocolate cake mix. I do prefer the flavor of the German chocolate cake mix, though. It has a sweeter, lighter taste.
You’ll also need melted butter or oil, brown sugar, 2 eggs and chocolate chips. So simple!
How To Make Cake Mix Brownie Bars?
These brownie bars are incredibly easy to make. Here’s how:
Prepare oven and baking pan: Preheat your oven to 350ºF. Spray a 9×13 inch baking pan or dish with nonstick cooking spray or line it with parchment paper.
Combine all ingredients in a large bowl, except chocolate chips.
Bake: Transfer the batter to the prepared baking pan and smooth out the top so that it’s one even layer. Sprinkle chocolate chips over the top. Bake for 20 to 25 minutes. The brownies should feel set on the edges, and a toothpick inserted into the center should come out mostly clean. I know some people enjoy their brownies undercooked, so feel free to remove these brownies, from the oven, early.
Cool and serve: Let the brownies cool in the pan for about 10 minutes, then cut into squares and enjoy!
Can I Add Nuts To This Brownie Recipe?
Absolutely! Finely chopped nuts like pecans or walnuts can easily be added to this brownie recipe. I recommend 1/2 to 2/3rds cup of chopped nuts. You can simply sprinkle them over the top with the chocolate chips or stir them into the batter.
Should I Use A Metal Or Glass Pan For Baking Brownies?
Either a metal or glass pan will work fine for baking brownies. For crispier crusts and edges, use a metal pan. For glass pans, you may need to add up to 5 minutes of baking time, but be sure to check on your brownies at the time suggested.
How Do I Store Leftover Brownies?
Store cut brownies in an airtight container at room temperature. They will last about 2 days at room temperature. You can transfer them to the fridge for another couple of days. If you do decide to store them in the fridge, I would suggest microwaving them before eating, so they aren’t dry.
Can You Freeze Brownies?
Yes you can freeze brownies! Cool them completely then transfer them to an airtight container and freeze for up to 3 months. When ready to serve, thaw at room temperature. I can attest to the fact that these are possibly even better once frozen and then microwaved (think melty chocolate chips and rich, fudgy center).
What Makes These Chocolate Chip Brownie Bars So Freaking Delicious?
In my humble opinion, these brownie bars are absolutely perfect and on my Top 10 List of best sweet treats ever. You’re going to love them because they’re:
